The correct answer is: D. Amendments to the Insurance Law Bill pending in the Rajya Sabha, were approved by the Cabinet.
The sentence is in the passive voice, so the subject of the sentence is the action being performed, not the person or thing performing the action. In this case, the action is “approved,” and the subject is “Amendments to the Insurance Law Bill pending in the Rajya Sabha.” The sentence could be rewritten in the active voice as follows: “The Cabinet approved amendments to the Insurance Law Bill pending in the Rajya Sabha.”
The other options are incorrect because they do not correctly reflect the structure of the sentence. Option A is incorrect because it uses the singular verb “was” to agree with the singular subject “Amendments.” Option B is incorrect because it uses the singular verb “was” to agree with the singular subject “Amendments to the Insurance Law Bill.” Option C is incorrect because it uses the prepositional phrase “by the Cabinet pending in the Rajya Sabha” as the subject of the sentence.
The sentence is grammatically correct and uses the correct verb tense. The sentence is also clear and easy to understand.
